fix(ext/http): Use brotli compression params (#19758)

Browse source 
Fixes #19737 by adding brotli compression parameters.

Time after:

`Accept-Encoding: gzip`:

```
real    0m0.214s
user    0m0.005s
sys     0m0.013s
```

`Accept-Encoding: br`:

Before:

```
real    0m10.303s
user    0m0.005s
sys     0m0.010s
```

After:

```
real    0m0.127s
user    0m0.006s
sys     0m0.014s
```
